Description

1-Propanesulfonic Acid, 1-Amino-2-Methyl- CAS NO 141044-68-0 is a specialized sulfonic acid derivative featuring both an amino and a sulfonic acid functional group. This unique bifunctional structure makes it a valuable intermediate for synthesizing high-performance surfactants, pharmaceutical compounds, and specialty polymers. It is particularly sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors for its role in creating zwitterionic compounds and functionalized molecules.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs), especially those requiring sulfonate or zwitterionic functionalities for enhanced solubility or bioavailability.
• Surfactant & Detergent Synthesis: Serves as a precursor for producing high-performance amphoteric and zwitterionic surfactants used in personal care products and industrial cleaners.
• Agrochemical Formulations: Used in the development of herbicides, fungicides, and plant growth regulators where its ionic properties can improve formulation stability and efficacy.
• Polymer Modification: Employed to introduce sulfonic acid groups into polymers, enhancing properties like hydrophilicity, ion-exchange capacity, or anti-static characteristics.
• Electroplating Additives: Functions as a brightening agent or stabilizer in electroplating baths for metals.
• Chemical Research & Development: A versatile reagent for organic synthesis, particularly in reactions where a protected or latent sulfonic acid group is required.

Quality Control

Every batch of 1-Amino-2-Methyl-1-Propanesulfonic Acid is manufactured under a strict quality management system. We provide comprehensive quality assurance, with product specifications tailored to meet the rigorous demands of pharmaceutical and fine chemical synthesis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment to ensure traceability and compliance with your internal standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product stability and performance.
